Serial No. 727,4o2.

To all whom it may concern Be it known that I, Fnnonnro CHARLES FARGE, acitizen of the Republic of France, and resident of Nice, France, haveinvented new and useful Improvements in Valve Mechanism for AutomaticGas Lighting and Extinguishing Apparatus, which improvements are fullyset forth in the following specification.

This invention relates to valve mechanism for automatic gas lighting andextinguishing apparatus.

Apparatus of this kind already in use necessitate, for insuringtightness of the gas chamber, either grinding keys, or diaphragms which,with time and the low temperatures, fail to operate or are injured, thusrendering the apparatus useless.

The present apparatus is so constructed as to be absolutely reliable andto work well for a very long time. It embodies, primarily, anoscillating rod controlled by an eccentric shifted by the clock-work,said rod being provided with two pointed metal plugs or valves whichcheck or afford a free passage for the gas, as required.

An embodiment of the invention is illustrated in the accompanyingdrawings, whereof:

Figures 1 and 2 are longitudinal, vertical sections taken at rightanglesto each other. Fig. 3 is a horizontal sect-ion on line AA, Fig. 1. Fig.4 is a part-sectional elevation of the whole device, showing analternative mounting for the rod.

In the drawings, 1 indicates the gas chamber secured by means of screwsto the case of the clock-work 15. The gas flows into this chamberthrough the nipple 2 and passes out through either the opening 3 or theopening 4, according as it is to be supplied either to the burner or tothe pilot light. A nipple 5 permits the attachment of the burner.

A rod 8, provided with a centrally-located metal ball 9, about which asa fulcrum the said rod is adapted to oscillate, carries at its upper endtwo pointed metal plugs or valves 6 and 7 the valve 6 being designed toclose the opening 3, and the valve 7 to close the opening 4. The lowerend of this rod is equipped with a fork 13 which straddles a groovedeccentric 14 fixed on the shaft 17 of the clock-work. The ball 9 isdisposed in a housing 10, and, in conjunction with the latter, serves toclose the gas chamber- 1, the said housing being held in place by. aclamping screw 11 and a lock-nut 12, which, however, in no way interferewith the oscillation of rod 8.

Instead of the arrangement just described, that shown in Fig. 4 may. beemployed, wherein the parts 11 and 12 are replaced by a spring 12' whichis disposed beneath a washer 11 and forces the latter against the ball9. This spring is housed within an externally-threaded sleeve 12 which,by being more or less tightened, enables a constant pressure on saidball to be obtained, and, at the same time, the wear, if any, to betaken up.

On shaft 17 (Figs. 1 and 2), is mounted a disk 16 which is provided withtwo notches, (Figs. 1 and2), by means of which a slide 18 designed toengage therewith, serves to hold the valve mechanism station'- aryeither in thelighting or in the extinguishing position. i

The clock-work, with which the apparatus is furnished, and whichcontrols the lighting and extinguishing of the pilot light and burner,may be of any preferred type. It forms, however, no part of thisinvention, and, hence, requires neither illustration nor description, itbeing considered suflicient' for present purposes to state that thevalve rod 8 is shifted thereby at the proper times, and that the slide18, which cooperates with the notched disk 16, as above mentioned, islikewise actuated therefrom. In other words, so far as the oscillationof the valve rod 8 is concerned, it is produced by,

the rotary movement of the eccentric 14, which acts directly upon fork13, the said movement of the eccentric being effected by the rotation ofthe disk 16 which, in turn, is produced by the action of the clock-work.During this oscillatory movement of the valve rod, the valves 6 and 7carried thereby operate to open one of the passages or openings 3 and 4and close the other, according to the direction of such movement, aswill be understood.

In the construction shown in Fig. 4, the upper part of the valve rod isin the form of a steel blade which is sufliciently flexible to preventit from'wedgingthe valve into its passage or opening, during itsmovementin one direction, and yet rigid enough to disengage said valve duringits return movement.

I claim as my invention 1. In a gas lighting and extinguishing apparatusthe combination of a gas chamber having inlet and outlet passageslocated one below the other; an oscillatory rod arranged therein andprovided at one end with a valve for controlling the outlet passage andintermediate its ends with a ball; a hollow bearing element disposed insaid chamber below said inlet passage and within which said ball ishoused, said bearing element having oppositely-located openings for theextension of said rod therethrough; and actuating means engaged with theother end of said rod.

2. In a gas lighting and extinguishing apparatus, the combination of avertical gas chamber having an inlet, and a pair of oppositely-locatedoutlets disposed above said inlet; an oscillatory vertical rod arrangedin said chamber and provided at its upper end with a pair of valvesadapted to be moved into and out of said outlets to close one and openthe other, said rod being provided intermediate its ends with a ball; ahollow bearing element wherein said ball'is housed havingoppositely-located openings for the extension of said rod therethrough,said bearing element being disposed in said chamber below said inlet;and actuating means engaged with the lower end of said rod.

3. In a gas lighting and extinguishing apparatus, the combination of agas chamber having inlet and outlet passages; an oscillatory rodarranged in said chamber and provided at one end with a valve forcontrolling the outlet passage, and intermediate its ends with a ball,said rod having its ballcarrymg portion rigid and 1ts valve-carrymgportion flexible; a bearmg element wherein said ball is housed disposedin said chamber; and actuating means engaged with the other end of saidrod.

4. In a gas lighting and extinguishing apparatus, the combination of agas chamber provided with inlet and outlet passages, and

having a portion of its interior wall threaded; an oscillatory rodarranged in said. chamber and having a valve at one end for controllingsaid outlet, and a ball intermediate its ends; a hollow bearing elementwherein said ball is housed disposed in said chamber; a spring bearingagainst said ball; a member adjustably mounted in the threaded portionof said chamber and incasing said spring for controlling the tension ofthe same; and actuating means engaged with the other end or" said rod.

5. In a gas lighting and extinguishing apparatus, the combination of agas chamber provided with inlet and outlet passages; an

oscillatory rod arranged in said chamber and having a valve at one endfor controlling said outlet, and a ball intermediate its ends; a hollowbearing element wherein said ball is housed disposed in said chamber; a79 presser member acting against said ball; means for controlling thepressure exerted by said member; and actuating means engaged with theother end oi said rod.

In testimony whereof I have signed this E. Corinna, E. RAYMOND.
